Tender calendar and system
The main and longer-term refinancing operations are conducted in accordance with an indicative calendar published by the Eurosystem. This calendar is published at least three months before the start of the year for which it is valid. When drawing up the calendar, due account is taken of bank holidays in the individual member states.
The Deutsche Bundesbank uses the Open Market-Tender-Operation-System (OMTOS) to conduct Eurosystem open market operations.
